A couple of years ago on plex supposedly implemented a fix for multi part episodes replaying
”Currently if you have a file labeled S01E01E02 and you play Episode 1 then both episodes play as a single continuous episode. After it finishes, it marks Episode 1 as Watched, then starts playing the exact same episode again because it thinks it’s “Episode 2”, which is obviously wrong.
What it now does is play the file labeled S01E01E02, then when it finishes it marks both Episode 1 AND Episode 2 as Watched, and then correctly starts playing Episode 3”
Its 2025 and this only works on some devices. For me it correctly marks the multi part episodes as watched and moves on to correct file on these devices
Plex Web
Plex HTPC
IOS
But on my Roku and Vizio tv it still replays the multi part episode. Please fix this feature so that that it works correctly on all devices. Anyone else with this problem on other devices please add to this list
